Definitions

• the invention relates to a stretcher for moving of injured persons, as defined in the preamble of claim 1.
• the main type of stretchers which have been in use for a long time consist of an elongated frame having handles at both ends.
• an element with a resting surface has been mounted, which surface is to support the one to be transported on the stretcher.
• the element can for example consist of a piece of cloth which has been tightly stretched in the frame or, with simpler stretchers, a piece of cloth hanging between two rods which form the side pieces of the frame.
• EP Bl 0 294 378 it is proposed to use a heat-insulating foam material having an integrated surface layer for the resting surface. In the first place a piece of this material is intended to form a mattress or lying underlay when resting in the field.
• the idea of using a lying underlay as an emergency stret ⁇ cher, when being in the field and where said underlay is always taken along, has advantages per se.
• the lying underlay is usually available in an emergency situation when somebody has been injured during field service and the insulating, somewhat-rigid but at the same time resilient, material provides good comfort and at the same time also the heat insulation which is often very important for the injured person.
• disadvantages also exist. If one makes a stretcher by inserting rods into holes in the piece of material, such rods accordingly have to be acquired or taken along already. In this way, an important advantage is lost in that the stretcher can be formed only by the lying underlay, which can easily be carried and is usually also used in the field.
• the carrying underlay is used only in carrying it by means of the holes at the edges, at least four bearers are required, two at each end. Even when four bearers are used, such a stretcher will be very uncomfort ⁇ able since the piece of material is bowed between the carrying points and the injured person is made to assume a hunched-up position. This can be very disadvantageous and it can severely aggravate the injury if this relates to some central part of the body, for example the backbone. Even if bearers are also available for the middle part of the piece of material, this underlay will produce an uneven surface and will change its shape all the time, particu ⁇ larly during transport on uneven terrain. This can also be very unfavourable in respect of certain injuries.
• the present invention aims at eliminating such disadvan ⁇ tages, so that a lying underlay or mattress of the said type can be used as a stretcher, with which a person can be transported in an out-stretched position without being in a hunched-up position or the body being subjected to conti ⁇ nuous changes of position during transport.
• the need for special rods having a greater length than the length of the body is eliminated.
• stiffening elements having a flat cross-section which can be divided into several shorter lengths, so that they can be rolled in into the piece of material during its trans ⁇ port.
• stiffening elements without any larger space requirement is obtained in that special channels for housing these elements are arranged in the piece of material.
• Fig. 1 one view of the stretcher arrangement in a spread- out condition
• Fig. 2 an end view of the stretcher arrangement as in Fig.
• Fig. 3 the stretcher arrangement in the condition of use when a person is to be transported therewith.
• the main part of the stretcher is formed by a piece of material 1. This has an upper side, which is shown in Fig. 1 and which is denoted as 2 in Fig. 2. Opposite to this is an underside 3. At least the underside must be water-impermeable since it is presumed that the stretcher might have to be put down on a damp base.
• the material in the piece 1 should be semi-stiff, elastically resilient in the surface, but only insignifi ⁇ cantly stretchable. It should not be absorbent and, as mentioned, especially not from the underside 3.
• cellular plastic has been mentioned, which cellular plastic should have closed cells.
• a dense surface layer should exist, suitably thicker at the underside 3 than at the upper side 2.
• a suitable thickness may be 5-10 mm in the foam part and up to about 1 mm in the surface layer.
• a polymer material such as polyethylene can be suitable.
• Two channels 4 run along the piece of material, said channels being formed in grooves 6 on the upper side 2 of the piece of material and being covered by attached material strips 5 at the upper side, which strips are preferably made of a semi-stiff material.
• the strips can be sewn to the piece of material.
• the grooves are shown here cut in through the foam layer to the thicker surface layer on the side 3 , this being a preferred embodiment.
• the piece of material 1 should have a length which corre- sponds to the length of the body of a man, say about 2 meters.
• the width between the channels 4 is adapted to the width of a human body plus two times half the thickness of the body. This is the ideal adaptation which should be derived from the body measurements of persons, for whom the stretcher is primarily intended, for example adult men of normal size. Persons who strongly deviate from this norm, for example children, can however also be advantageously transported on the stretcher.
• These ends may be provided with substantially semi-circular shaped cuts 10, which make it possible to insert one's hand when the stretcher it to be carried. Such cuts can also be made along the side edges so as to form further carrying handles 11.
• a number of straps 12 are arranged which are provided with tensioning devices so that they can be tightened in pairs.
• a connection by means of velcro bands is indicated, but clasps can alternatively be used.
• Stiffening elements 15, 16 can be housed in the channels 4 (see Figs. 2 and 3) .
• the stiffening elements may be divided into shorter lengths, if these are laid in an overlapping relationship. As is indicated in Fig. 1 they may for example be divided into two lengths 15 and 16 together being about 20 cm longer than the channels 4. When in place in the channels 4, the element sections are laid as shown in Fig.
• a suitable attachment of the stiffening elements is that one of the parts, here denoted 15, is inserted in its channel from the head end.
• the other part 16 is inserted into an opening 17 (Fig. 1) in the band 5 approximately midway between the head and foot ends.
• stiffening elements 15, 16 are made flat is that they should occupy less space, but also for the reason that if they are lying in the channels 4 and the stretcher device is used spread-out as a lying underlay, they should not form noticeable protrusions on the upper side. In order that they can actually function as stiffen ⁇ ing elements they must, when being used, be kept on their ends so that the higher bending stiffness of the width section is made use of. How this is obtained is shown in Fig. 3.
• the material piece 1 is here folded for transport of a person, the body section of which is indicated with a chain-dotted line 18.
• the channels 4 Since the width between the channels 4 is the width of the body plus approximately two times half of the body-depth the channels 4 will be located at the parts which extend along the sides of the body of the person and which are thereby approximately vertical when seen in cross-section if the stretcher is carried with the handgrips 10 and possibly also 11. The parts of the material piece where the channels are located will also receive a certain support in their upright positions by the body of the person which is carried. For persons having body measurements which greatly deviate from the ones to which the dimensions of the stretcher have been adapted, the channels 4 can come higher up than shown in Fig. 3 for small body sizes. When however the stretcher is to be carried by the handgrips 10 and possibly 11 which are located above the channels in the carrying position, the stiffening elements 15, 16 will nevertheless be standing on their edges in the channels.
• the outer parts outside the channels 4 can be bent in over the body of the person towards its upper side and the edges can be connected by the straps 12. In this way the person is protected from falling out if the stretcher for example were to be lifted at a steep angle or vertically, and due to its tube shape it will have a more rigid form.
• the channels 4 are well adapted to the stiffening elements 15, 16 so that they do not have enough space to lie on their sides but are securely held on their edges when the stretcher is carried. This is of course especially important if the stiffening element has been divided into sections, in the joints of which the element should be able to bend if its overlapping parts are not held well-fixed in their respective channels.
